Class InformationNumber: 257/654Name:Active solid-state devices (e.g., transistors, solid-state diodes) > With specified shape of pn junction > Interdigitated pn junction or more heavily doped side of junction is concaveDescription: Subject matter wherein the device has at least one pn junction which is interdigitated (i.e., in which plural layers or fingers of n type material alternate with plural layers or fingers of p-type material, with then-type layers or fingers being parts of a single unitary n region and the p-type layers or fingers being parts of a single unitary p-region).
